TQ allwhom t may concern.' y

Be it known that I, ISRAEL BENJAMINS, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented anew and use-- ful Means for Securing l/Vindow Sashes in the ingress of burglars and the falling out of children therethrough g Second: To enable the securing of the window sashes to be accomplished by afsingle` stroke or movement ofthe hand, also the releasing of the window `sas-hesto be accomplished in the same way; and

Third: To have said means light, simple,

durable and inexpensive. i

I attain these objects by the device.` illustrated in the accompanying` drawings or byV any mechanical equivalent or obvious modifcation of the same.

In the drawings Fig. 1 is a front view of my means for securing window sashes in position; Fig. 2 is a side view, from left to right in Fig. 1, of the same; Fig. 3 is a section on the line A-B of Fig. 1. v i a Similar numeralsl refer to similar parts throughout the several views: 11 designates a tubular member having at one end there- .i

of the shoulder 11L abutting against the plate 16 and the flange 11? expanded intothe recess 16 of said plate 165the main body of said member 11 is threaded to lit the nut 12, and said member terminates at the other end in the prism 18 which is shown in Fig. 1 as octagonal, but which may have any other shape, and which lits ythe opening in the handle or wrench 19. i

Said nut 12 is provided with a basell,

which may be secured to `the top of the iii-` ner sash 111 by means of suitable wood screwsthrough the screw-holes 15.

rIhe plate 16 is adapted to bear against the outer sash 17 when the member 11 is moved forward by turning the handle 19 in the proper direction, thereby pressingthe sashes 14C and 17 against the/weather strips 21 and 2O respectively.y e i The force applied to the handle 19 is multiplied the screw thread until the(y frictional resistance to moving the sashes is sufficiently great 'to secure them in place.

22 designates part of the jamb, and 23 the inner guide strip; 2e and 25 are the grooves for the sash cords to pass therethrough. i

C It is evident that, when the pitch of the thread on the member 11 `is large enough, a

singlestroke or turning movement of the handle 19 through an arc of less than 180 degrees will advance the plate 16 su'l'hciently `to lockv the sashes in position.

By making the member 11 tubular greater lightness is secured for a given diameter and pitch thereof.`

rIhe handle 19 may beeither permanently i secured to themember 11 or made detachable when it is desired to prevent children from manipulating the same; the handle 19 may `also bewmade in one with said `member 11.

There the flange 11b may `be expanded y sufficiently, the plate lmay be omitted, al-

though the operation of the device would be` `more perfect with the plate 16 than without it. i i

I prefer to have the plate 16 freely swiv-y elled on theend of the member 11 between the shoulderlla and the flange 11b; but it may also be` fastened thereto.

Many other changes could be made in my f y means for securing window sashes in position without departing from the main scope 'of myinvention,

I do not, therefore, restrict myself tothe details as shown; but I intend to include also all mechanical equivalents and reasonably i ,obvious modifications of the saine within the `scope ot my claims.

WhatI claim as mly invention, and desire to secure by Letters atent is:

l. 4In a means for securing window sashes in i,

position a tubular member terminating at the inner end thereof in a prism, a thread of a suitable pitch on the exterior of said member, a nutadapted to t said thread, and to be secured to the inner sash a handle having adapted to turn the same through part of a ,therein a prismatic opening whereby it may `be detachably connected to said member and iois revolution andto cooperatewith said thread and nut to advance said member, byits motion through a part of arevolution, and to vcause it to bear against the outer sash.

2. Ina means for securing window sashes in position a nut, a hollow threaded member adapted to fit said nut, a plate at thev forward endv of said member, a recess in 'said plate, a flange at the forward end of said member expanded into said recess, a shoulder or offset at the forward end of the threaded portion of said lmember, said plate 1 being engaged with said member between said shoulder and saidange, and av handle l0 adapted to turn said member, thereby bringing said plate to bear against one of the sashes, thereby securing it in place.
